It's been a longtime frustration of me that it's not possible to play European football in the first year of manager mode, though it is perfectly possible in the game mode 'the season'.
Now I have found a way to fix that problem, without any editing.
First, you start 'be a pro' with whatever team you want to start a carreer in manager mode. You select an existing player, and whatever European cup you want to play in. Then you save this, and exit right away.
Next step: start a carreer in manager mode with the same team. That's it. You have European football.
I'm currently only in my first season, so I don't know if there might be trouble at the end of the season. I also don't know if the winner of the cup in the first year is automaticly in the cup in the second year. For as far as I know it only works on PC.
Good luck!
